A further object of the invention is to provide an eye protector which is inexpensive, strong and durable, and which is constructed of material which can be easily cleansed and made sanitary after being Worn.

Referring to the drawings, A represents an eye cup circular in form and having one side thereof elongated diagonally to the axis thereof. This eye cup is preferably made of ber, although other material, such as metal, rubber, or the like, may be used, if desired.

Fitted inside of the circular end of this eye cup is a lens holding rim which is formed of metal, havinga ring a held in place by frictional engagement with the cup. This ring a is provided with an outwardly extending shoulder a1 which rests upon the edge or end of the eye cup, and upon which shoulder the` glass or lens a2 rests when in position.
